The current situation is fairly confusing, where an integer is interpreted
as a percent until you slap a decimal on it and magically it becomes an
absolute value.
Let's have a flag day in 14.0 and remove this shim entirely. Setting with
percent can still be useful, so allow a trailing '%' to indicate as such.
As a side effect, we tighten down the format allowed in the volume a little
bit by ensuring there's no trailing garbage after the value once it's
separated into left and right components.

AEAD ciphers for IPsec combine both encryption and authentication. As
such, ESP configurations using an AEAD cipher should not use a
seperate authentication algorithm via -A. However, this was not
apparent from the setkey manpage and 12.x and earlier did not perform
sufficient argument validation permitting users to pair an explicit -A
such as SHA256-HMAC with AES-GCM. (The result was a non-standard
combination of AES-CTR with the specified MAC, but with the wrong
initial block counter (and thus different keystream) compared to using
AES-CTR as the cipher.)
Attempt to clarify this in the manpage by explicitly calling out AEAD
ciphers (currently only AES-GCM) and noting that AEAD ciphers should
not use -A.
While here, explicitly note which authentication algorithms can be
used with esp vs esp-old. Also add subsection headings for the
different algorithm lists and tidy some language.

representing only one specified geom and optionally its parents. It
uses existing GEOM control interface, extended with new "getxml" verb.

The gunion(8) utility is used to track changes to a read-only disk on
a writable disk. Logically, a writable disk is placed over a read-only
disk. Write requests are intercepted and stored on the writable
disk. Read requests are first checked to see if they have been
written on the top (writable disk) and if found are returned. If
they have not been written on the top disk, then they are read from
the lower disk.
The gunion(8) utility can be especially useful if you have a large
disk with a corrupted filesystem that you are unsure of how to
repair. You can use gunion(8) to place another disk over the corrupted
disk and then attempt to repair the filesystem. If the repair fails,
you can revert all the changes in the upper disk and be back to the
unchanged state of the lower disk thus allowing you to try another
approach to repairing it. If the repair is successful you can commit
all the writes recorded on the top disk to the lower disk.
Another use of the gunion(8) utility is to try out upgrades to your
system. Place the upper disk over the disk holding your filesystem
that is to be upgraded and then run the upgrade on it. If it works,
commit it; if it fails, revert the upgrade.
Further details can be found in the gunion(8) manual page.

After downloading the firmware to a device, it's inquiry data likely
will change. Force a rescan of the target with the CAM_EXPECT_INQ_CHANGE
flag to get it to record the new inqury data as being expected. This
avoids the need for a 'camcontrol rescan' on the device which detaches
and re-attaches the disk (da, ada) device. This brings fwdownload up to
nvmecontrol's ability to do the same thing w/o changing the exposed
nvme/nvd/nda device. We scan the target and not the LUN because dual
actuator drives have multiple LUNs, but the firmware is global across
many vendors' drives (and the so far theoretical ones that aren't won't
be harmed by the rescan).
Since the underlying struct disk is now preserved accross this
operation, it's now possible to upgrade firmware of a root device w/o
crashing the system. On systems that are quite busy, the worst that
happens is that certain operaions are reported cancelled when the new
firmware is activated. These operations are retried with the normal CAM
recovery mechanisms and will work on the retry. The only visible hiccup
is the time that new firmware is flashing / initializing. One should not
consider this operation completely risk free, however, since not all
drives are well behaved after a firmware download.

Normally fsck_ffs never does reads or writes that are not aligned
to the size of one of the checked filesystems fragments. The one
exception is when it finds that it needs to write the superblock
recovery information. Here it will write with the alignment reported
by the underlying disk as its sector size as reported by an
ioctl(diskfd, DIOCGSECTORSIZE, &secsize).
Modern disks have a sector size of 4096, but for backward compatibility
with older disks will report that they have a sector size of 512.
When presented with a 512 byte write, they have to read the associated
4096 byte sector, replace the 512 bytes to be written, and write
the updated 4096 byte sector back to the disk. Unfortunately, some
disks report that they have 512 sectors, but fail writes that are not
aligned to 4096 boundaries and are a multiple of 4096 bytes in size.
This commit updates fsck_ffs(8) so that it uses the filesystem fragment
size as the smallest size and alignment for doing writes rather than
the disk's reported sector size.

Since 59f256ec35 dmesg(8) will always skip first line of the message
buffer, cause it might be incomplete. The problem is that in most cases
it is complete, valid and contains the "---<<BOOT>>---" marker. This
skip can be disabled with '-a', but that would also unhide all non-kernel
messages. Move this functionality from dmesg(8) to kernel, since kernel
actually knows if wrap has happened or not.
The main motivation for the change is not actually the value of the
"---<<BOOT>>---" marker. The problem breaks unit tests, that clear
message buffer, perform a test and then check the message buffer for
a result. Example of such test is sys/kern/sonewconn_overflow.
Part of the problem was that fsck_ffs would read the superblock
multiple times complaining and repairing the superblock check hash
each time and then at the end failing to write out the superblock
with the corrected check hash. This fix reads the superblock just
once and if the check hash is corrected ensures that the fixed
superblock gets written.

Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.
Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

Add two underscore characters "__" to names of BIT_* and BITSET_*
macros to move them to the implementation name space and to prevent
a name space pollution due to BIT_* macros in 3rd party programs with
conflicting parameter signatures.
These prefixed macro names are used in kernel header files to define
macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h.
If C programs are built with either -D_KERNEL (automatically passed
when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET
(or this macros is defined in the source code before including the
bitset macros), then all macros are made visible with their previous
names, too. E.g., both __BIT_SET() and BIT_SET() are visible with
either of _KERNEL or _WANT_FREEBSD_BITSET defined.
The main reason for this change is that some 3rd party sources
including sched.h have been found to contain conflicting BIT_*
macros.
As a work-around, parts of shed.h have been made conditional and
depend on _WITH_CPU_SET_T being set when sched.h is included.
Ports that expect the full functionality provided by sched.h need
to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if
BIT_* macros are defined in that program, too.
This patch set makes all of sched.h visible again without this
parameter being passed and without any name space pollution due
to BIT_* macros becoming visible when sched.h is included.
This patch set will be backported to the STABLE branches, but ports
will need to use -D_WITH_CPU_SET_T as long as there are supported
releases that do not contain these patches.

As far as we know, there is no FAT implementation that supported hard
links, and our msdosfs driver assumed one cluster chain is only
referenced by one directory entry and clears it out when the file is
deleted. On the other hand, the current code would proceed with
checkchain() when the directory entry's head cluster is a valid numbered
cluster without checking if it was a valid head node of a cluster chain.
So if the cluster do not being a chain (e.g. CLUST_FREE, CLUST_BAD),
or was already referenced by another directory entry, this would
trigger an assertion in check_chain() at a later time.
Fix this by giving the user an option to truncate the directory entry
when the head cluster is an invalid cluster, an visited head node,
or not a head node.

Geom utilities (geli(8), glabel(8), gmirror(8), gpart(8), gmirror(8),
gmountver(8), etc) all use the geom(8) utility as their back end
to process their commands and pass them into the kernel. Creating
a new utility requires no more than filling out a template describing
the commands and arguments that the utility supports. Consider the
specification for the very simple gmountver(8) utility:
struct g_command class_commands[] = {
{ "create", G_FLAG_VERBOSE | G_FLAG_LOADKLD, NULL,
{
G_OPT_SENTINEL
},
"[-v] prov ..."
},
{ "destroy", G_FLAG_VERBOSE, NULL,
{
{ 'f', "force", NULL, G_TYPE_BOOL },
G_OPT_SENTINEL
},
"[-fv] name"
},
G_CMD_SENTINEL
};
It has just two commands of its own: "create" and "destroy" along
with the four standard commands "list", "status", "load", and
"unload" provided by the base geom(8) utility. The base geom(8)
utility allows each command to use the G_FLAG_VERBOSE flag to specify
that a command should accept the -v flag and when the -v flag is
given the utility prints "Done." if the command completes successfully.
In the above example, both of the commands set the G_FLAG_VERBOSE,
so have the -v option available. In addition the "destroy" command
accepts the -f boolean flag to force the destruction.
If the "destroy" command wanted to also print out verbose information,
it would need to explicitly declare its intent by adding a line:
{ 'v', "verbose", NULL, G_TYPE_BOOL },
Before this change, the geom utility would silently ignore the above
line in the configuration file, so it was impossible for the utility
to know that the -v flag had been set on the command. With this
change a geom command can explicitly specify a -v option with a
line as given above and handle it as it would any other option. If
both a -v option and G_FLAG_VERBOSE are specified for a command
then both types of verbose information will be output when that
command is run with -v.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.
